To all whom it may concern:

Be it known that I, EDWIN H. Fonn, a citizen of the United States, residing at New Bedfo-rd,.in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Hand-Thread- 'ing Antisuction-Shuttles, of which the folinvention consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended claims.

In the accompanying drawings :'Figure 1 is a top plan View of the threading end of Fig. 2 is a bottom plan view thereof. Fig. 3 is, a side elevation, illustrating one step in the process of threading the shuttle. Fig. 4'

is a. top plan view of a modification of the threading end of a shuttle. Fig. 5 is a longitudinal section takenon'the line 5-5 of Fig. 4. Fig. 6 is an elevation of a threading device used in threading the shuttle, and

Fig. 7 is a sectional view taken on the line 7-7 of Fig. 6.

Referring to the drawings for a more particular description of the invention, 1 indicates the shuttle provided with theusual shuttle eye 2. In carrying out-the present invention the bottom of the shuttle is also provided with the eye 3 which is directly in line and concentric with the eye 2. The eye 3 has formed in itswall the niche or slit 4 extending in a direction toward the shuttie tip 5.

' The numeral 6 indicates the side eye which extends laterally through one side of the shuttle'and communicates with the eye 2.

7 indicates the threading device com rising the handle 8, the wire shank 9 provided at its outer end with the inwardly bent hook 10, and the resilienttip '11 of cork at the inner end of the handle. The top of the handle is flattened as at 12, on the plane of the hook 10. T

In threading the shuttle, the shank 9 of sense of feeling,

eyes 3 and 2 in the manner illustrated in Fig. 3 with the tip of the handle fitting in the eye 3, whereby the device is held in the shuttle with the flattened side 12' of the handle 8 upward or toward the nearest tip of the shuttle, thus giving the operator, by the proper position of the hooked end of the shank. The operator then takes up the shuttle for refillin leaving both hands free for the raising of the spindle, the removal therefrom of waste and tube, and the replacing of a new filling. The loose filling end is' then passed over the hooked end of .the shank, and the device drawn backward until free of the shuttle followed by a slight upward movement to engage the filling in the slit 4 of the eye 3. The book is then inserted in the side eye 6 to engage the filling inside the shuttle which is "then drawn through, completing the'oper- 'ation. a shutttle embodying my improvements.

While a shuttle constructed as shown in Figs. 1 to 3, cannot ordinarily be threaded by suction, yet this could be accomplished by placing the finger over the eye 3, and

therefore. to obviate this possibility and make the shuttle an absolutely anti-suction one, a downwardly inclined passage 13 is formed in the slanting wall 14 of the filling runway, which acts. as a vent for the shuttle eye. It is not possible to cover the passage- 13 with the finger tip owing to the narrowthe threading device is passed through the ness of the runway at the point pierced by Q said passage.

From the foregoingdescription taken in connection with the drawings itis thought that the construction and-advantages of this invention will be readily understood without requiring a more extended explanation.

Having described my invention what. I

claim as new and desire to secure by Letters Patent, is:

1. An anti-suction shuttle of. the class described provided with a shuttleeye communicating with the shuttle throat and in its bottom with an outwardly flared e ecommu-- nicating with the shuttle eye an provided in its wall with a slit extending in a direction toward the shuttle tip, said shuttle also having .a side eye communicating with the shuttle eye and a downwardly inclined passage extending through the wall of the fillingrunway to the shuttle eye and acting as a vent to avoid possibility of threading the In testimony whereof I affix my signature shuttle by suction. 111 presence of two Witnesses.

2. An anti-suction shuttle provided With 7 an eye communicating with the shuttle IN FORD 5 throat, en exit side eye in communication Witnesses:

with said eye and an inclined passage ex- JOHN J. ROLmiqs,.

tending from the throat to one of said eyes. 'ELIJAH R. CRovELo.
